The liquid flows from the filter bag to the outside of the bag, and the filtered particles are intercepted in the bag. The working principle of the bag filter is pressure filtration. The bag filter system mainly consists of three parts: filter container, support basket and filter bag.
Usually, the PE/PP filter bag filter precision unit is expressed by the number of "microns" (microns), while the nylon filter and stainless steel filter precision unit is expressed by the number of "eyes".
"Mesh" refers to the number of holes per square inch (25.4 mm per square inch) screen mesh. 50 meshes refers to 50 holes per square inch and 500 meshes per square inch. The higher the number of meshes, the more holes there are. Besides the number of holes in the screen, it is also used to indicate the particle size through the screen mesh, the higher the number of meshes, the smaller the particle size.
From the definition of "mesh" above, it can be seen that the size of aperture is related to the diameter of yarn used for weaving filter cloth. In practical use, it is also related to monofilament, polyfilament and weaving method. At the same time, the rotational speed of centrifuge (the force of centrifuge), the performance and temperature of filter material are also related to the speed of centrifuge used, so it is also a good choice of filter bag suitable for its own working conditions. Very complex selection process.
